MEET OUR FOUNDER
The frustration that started it all
Hey there! For years, we sought to find a pair of jeans that fit. Like actually fit. All. Day. Long. We started KarinaJ because we deserve jeans that don’t punish us when we treat ourselves to some extra dessert, skip the gym, or are bloated from our periods.
So we engineered something better: Slip-on jeans with real denim and a hidden, leggings-soft stretch waistband underneath.
Real comfort is a pair of jeans that adapt with you — full, bloated, on your period — and never makes you think about it again.

Jeans were never the problem The way they
were built was.

In January 2023, I flew to New York to attend Kingpins, the world's largest sustainable denim trade show. I didn't go with a finished plan—just a lot of questions. That trip introduced me to the world of denim manufacturing and helped me realize this wasn't a fashion problem; it was a product problem. Women’s bodies change constantly, yet most jeans are designed to fit only a single moment in time.
Over the next year, I immersed myself in denim development. My house filled with fabric swatches as mills mailed samples back and forth. I partnered with a former Levi's designer to begin developing the concept and evaluating countless fabric options, construction techniques, and fit approaches in search of a solution that could deliver both comfort and a premium denim look
Once the concept was established, I focused on perfecting the execution. I worked through six rounds of prototypes and hosted extensive fit sessions to understand how the jeans performed on different body types. Alongside a technical designer from Athleta, I refined everything from the waistband construction to the fit and recovery of the denim, making improvements with each iteration.
The final year was dedicated to preparing for launch. I went through two manufacturers before finding one capable of producing the jeans to the quality standard I envisioned. After 3.5 years of development, I launched on Kickstarter in February 2026 and generated more than $10,000 in preorders within 72 hours. Women immediately responded with comments like, “I wish I could take these home today.”
